Abstract: Renin–angiotensin–system (RAS) activation plays a key role in the development of hypertension and cardiovascular disease. Drugs that antagonize the RAS (angiotensin-converting enzyme [ACE] inhibitors and angiotensin receptor blockers [ARBs]) have proven clinical efficacy in reducing blood pressure values and cardiovascular morbidity and mortality. ACE inhibitors partially inhibit plasma ACE, and angiotensin II generation. Thus, ARBs, which block selectively type 1 angiotensin II receptor (AT1R), have been developed and used in the clinical management of hypertension and cardiovascular disease. Experimental and clinical trials with ARBs indicate that this class of drug represents an effective, safe and well tolerated therapeutic option for the prevention and care of hypertension, even though there is no proven superiority as compared to ACE inhibitors except for the better tolerability. Most ARBs may not completely inhibit the AT1R at the approved clinical doses. Azilsartan medoxomil is a newly approved ARB for the management of hypertension. This ARB induces a potent and long-lasting antihypertensive effect and may have cardioprotective properties. This article reviews the current evidence on the clinical effectiveness of azilsartan in hypertension.
